2 re resents a stationary to 1 section of the pr ucer, and 3 is a movabe lower section which is suspended or hung on the suspension rods 4 fromthe cran pins 5 on the cranks 6. The cranks 6 are mounted on the ends ofshafts 7 which are rotatably mounted in bearings 8 on top of or abovethe stationary section 2 of the gas reducer. Each of the shafts 7 isprovidewith a worm wheel!) which meshes with and is caused to rotate bysuitable worms secured on the driving shaft 10. The shaft 10 isconnected by slowdown gearing 11 with a motor 12, by which the movablebottom section of the producer is actuated. The top section 2 of theproducer is provided with a gas outlet opening 13, and with a fuel inletopening 14, which is ordinarily closed by means of the bell 15. Openings16 forming peep-holes are provided in the top part of the producer,these openings also being employed for the insertion of rods used inpoking the fuel bed when such poking operation is found necessary ordesirable. The top cover plate of the producer is formed of a panshapedcasting which is kept cool by means of the pool of water maintainedtherein. The openings 1-6 through the cover plate are closed by suitablecovers 17 when the producer is in operation. The lower end of the topsection 2 of the producer is provided with a bottom casting 18 formingan annular water trough. The top end of the bottom section 3 of thisproducer is provided with an inwardly and downwardly extending flange19, which projects downwardly into the water trough formed by thecasting 18,

so as to form and maintain awater seal between the stationary topsection 2 of the producer and the movab c bottom section 3 and form agas-tight joint between the sections. Water is supplied to the troughformed in the casting 18 in any desired mannor. and an overflow pipe 24is provided by which surplus water is carried away from the trough 18,the water overflowing from this trough into the pocket 25 with which thepipe 24 is connected. The lower end of the movable section 3 of theproducer terminates in a casting 20 having :1 flange 20 which projectsdownwardly below the level of the water maintained in the ash it 21. toprovide a water seal at this poi-ntm the producer. The ash pit 21 isprovided with a suitable overflow outlet 22, which maiutains the waterin the pit at the desired level, and the producer is provided withaciroular bottom plate 23 in e ash it on which the ashes are supported,the as mes in turn sup porting the column of fuel extending up wardlyinto the upper portion of the producer. In the lower portion of theproducer is a wind box 26 which is supplied with air under pressurethrough the pipe 27, which connects the wind box 26 with a fan or othersource of air supply. The air is forced through the annular openingsbetween the plates 28 fOl'flllI] the sectional top for the wind box 26,an rising upwardly through the ash bed into the burning fuel, assist inburning and converting the solid fuel into a combustible gas. The topsection 2 of the producer is provided with brackets 29 by which theproducer is carried on the supporting beams 30 extending transversely below the top of the producer. The movable lower section 3 of the reduceris connected by a ball and socket joint with the lower end of the rod 4and the upper ends of these rods are connected by cleviscs 31 and links32 to the crank pins 5 on the cranks (i. The movable lower section 3 ofFig. 3 is provided at a plurality of points on its upper end withsupporting rollers 33, which are arranged to turn by contact with thecam surface 34 of the rotatable ring 35. This ring, which tilts themovable section 3* of this producer, is mounted upon and rotates on theanti-friction rollers 36, which are secured in suitable bearings in thesupport 37. The ring 35 is provided on its periphery with bevel gearteeth 38, which mesh with the teeth in the bevel pinion 39 on the shaft40. Mounted on the shaft 40 is a worm wheel 41, the teeth of which meshwith the worm i2 which is directly connected to the armature shaft ofthe driving motor 43 by which the ring 35 is caused to rotate.

The gas producer shown in Figs. 3, 3 and 4 is provided with a gas outletopening, fuel inlet 0 ening and poking holes similar to those 5 own inFigs. 1 and 2, and a water seal is maintained between the top and bottomsections of the producer and between the lower end of the lower sectionof the producer and the ash pit in a similar manner to that shown in Fis. 1 and 2, and the construction of the win box. bottom plate andstationary top section of the producer is the same as that shown inFigs. 1 and 2.

In the construction shown in Figs. 5, 5 and 6, the stationary topsection 2' of the producer is mounted upon brackets and is supported bymeans in a similar manner to that shown in the receding figures. Themovable bottom section 3 is sus ended upon rods 4" in a manner similarto t at shown in Figs. 1 and 2. In this construction, however, the rods4" are used solely for supporting the movable bottom section 3" of theproducer and rotary vertically disposed shafts 14 are provided, havingcranks 45 on their lower ends for moving the bottom section 3"relativcly to the to section 2". The cranks 45 are provided with crankpins which project vcrtmally downward into the bearings 46, which aresecured to and form part of the movable bottom section 3 of theproducer.

The upper ends of the shafts 44 are provided with worm wheels 46, theteeth of which mesh with the worms 4.7, mounted on the shaft 48. Theshaft 48 is connected by slowdown gearing 49 with a driving motor 50 bywhich the movable bottom section of this producer is actuated. Thestationary top section of the producer is provided with gas outletopenings and fuel inlet openings, and. with poking or peep holesconstructed in a similar manner to that shown in the preceding figures.The producer is also provided with a wind box and with a water sealedash pit of similar construction to those shown in the preceding figures,the lower end of the movable section 3* of the producer projectingdownwardly below the level of the water in the ash pit to provide thenecessary water seal. The upper end of the lower movable section 3 ofthis producer is provided with an annular casting forming a watertrough,and the lower end of the stationary top section of the producer isprovided with a depending flange which projects downwardly into thewater in the trough so as to form a water seal.

In the modification shown in Figs. 7, 8 and 9, a gas producerrectangular in horizontal cross-section is shown, which is attached toand forms one end of a heating furnace. The stationary to section 2" ofthe producer is provided wit a side inlet 51 through which the fuel isdelivered into the producer, and suitable openings 52 are provided inthe side of the producer through which the fuel bed can be observed andstirred when necessary. The lower end of the stationery top section 2 ofthe producer is provided with a water trough formed by the casting 53 ina somewhat similar manner to that shown in Figs. 1, 2, 3 and i. Thestationary top section 2 of the producer is carried by means of brackets54 on the supporting stands 55. Supported below the top section 2 ofthis producer is a movable bottom section 3. lhc movable section 3 isprovided with trunuions 56, which are mounted in bearings 57,securcd onthe stands 55, so as to ermit of the bottom section 3* being rocker oroscillated. The marginal top edge of the section 3 is provided with :1depending flange 58 which projects dowu wardly into the water in thewater trough so as to maintain a water seal betwecn the stationary tosection and the movable bottom section 0 the producer and prevent escapeof the betweenv the sections. The lower end 0 the movable section 3 prwjects downwardly into the ash upa so as to form a water sea in a mannersimilacto that shown in the preceding figures. A wind box '30 isprovided in the lower ortion of the producer, in this case the wind boabcm rectangular in cross-section and being d1- vided into a plurality ofcompartments Q0, 60", 00, 60, 60, 60. An air pipe 61 which is providedon its one end with branches 62 is arranged to connect the severalcompartments in the wind box 60, and supply these compartments with airunder pressure. The air is forced outwardl from the box through the oenings 64 In the sides of the wind box on passing through the ashes,finally reach the burning fuel bed located in the producer above the ashbed.

In the operation of the gas producers shown in the drawings, the fuel issupplied to the producer and the ashes are removed from the water sealedash pit in the usual manner. After the fuel bed has been ignited and themaking of gas has been started, the

lower movable section of the producer is caused to move relative to thestationary top section.

In l, 2, 3 and 4, the bottom section is lifted so as to cause a verticalmovement of the fuel and ashes in the bottom section of the producerrelative to the fuel in the top section and the ash bed beneath theproducer.

In Figs. 5 and 6 the fuel in the lower movable section 3 is movedtransversely and bodily relative to the fuel in the top section 2". Byreason of the suspension rods P there is also a slight vertical movementof the lower section and its contents.

In the modification shown in Fi 7, 8 and 9, the lower section of the proucer is rocked or tilted relatively to the stationary top section 2,this mot-ion being imparted from the motor 65 through the train ofslowspeed gearing 66, the last wheel 66 of this train having a itmanconnection 67 with the movable section 3*.

As the bottom section is moved relatively to the top section, the columnof fuel is caused to gradually descend in the producer and finally, inthe form of ashes, reaches the open lower end of the lower movablesection of the producer.

When the movable section is actuated the ashes in the lower part of thesupporting ash bed are moved sidewise from beneath the movable sectionof the producer from which pointthey are removed by hand by the operatorat suitable intervals. As fuel is consumed fresh coal or other solidcarbonaceous material is added to the top of the bed through the fuelinlet opening in the producers and in moving the lower section of theproducer relatively to the top section one section or zone of the fuelis movct bodily relatively to another auction or zone of the fuel bedand 0 innings or holes forming through the fuel 10d are broken up andare caused to close, and in this way the fuel is caused to burnuniformly throughout the producers and the formation of lean gases isprevented.

The at lvantagos of my invention will be apparent to those skilled inthe art. The movable bottom section of the producer causes the fuel todescend evenly in the producer and prevents the formation of openingsthrough the fuel bed, such holes resulting in the formation of lean,poor ases, while the moving lower end of the ottom section of theproducer causes the ashes to be gradually moved from the bottom portionof the column of ashes supporting the combustible fuel in the producer.

Modifications in the construction and arrangement of the parts may bemade without departing from my invention. The manner in which the lowersection of the producer is moved relatively to the top section and theapparatus by which it is moved may be changed. The construction of thewater seal between the sections may be modified and other changes may bemade.
